Thanks Greg. I think I answered my own question. I've heard from another person here that some schools for the first belt just have you do proper ukemi and not get yourself hurt from the attack. My test I think (correct me if I'm wrong) seemed pretty comprehensive. But each dojo is different like you said. It also took me 9 or 10 months to be able to do it and pass it doing a good job. Thanks for your nice answer.

yeah, I was thinking that. I guess it changes with adults. Yeah, and I was a teen in Tae Kwon Do, those were "junior belts" (kids belts). I hear in aikido there are striped kids belts too under nanakyu (shichikyu) or rokku . I'm not sure if they mean anything. Wing Chun kung fu is also taught at our dojo by a different instructor. My instructor has been practicing Wing Chun also now for 5 years. So he incorporates that, the bridges, and striking into our aikido. He encourages us to use atemi whenever possible. I do Seidokan Aikido. But it is not directly Seidokan, it is his style, a more "realistic" self defense, Aikido with a light mix of kung fu principles strung in.

In the Wing Chun there are junior belts, and i think each one has a different title like my Tae Kwon do. Wow, things do change as you grow up, heh. This is my only martial art since I was younger.

You know something else I noticed Greg?

In the kung fu class, the kids are promoted faster than the adults. It takes the adults much,much longer to advance.

In my Tae Kwon Do school as a teen, I was very good, but it only took 3 months to advance each belt. Perhaps that's usual for a tae kwon do school, it was definitely not a McDojo.

Aikido on the other hand, Aikido i've been doing for 12 months, 9 months on a consistent basis, the rest illess and one AC/seperation from Aikido which took months to recover.
It took me 9 months to test for my first belt, rokkyu, and 1 or 2 months from white to yellow in tae kwon do. Is Aikido just harder? Is it harder than Karate? I was in Karate too.
Or is it just that kids are always going to advanced faster than adults ? ( more $$?)
